There is a WCF (Windows Communication Foundation) service PassGuideService.
PassGuideService is configured to accept messages that are encrypted and signed.
There is a client PassGuideClient that is using PassGuideService.
PassGuideClient is not working well. It is not receiving proper responses from PassGuideService.
To troubleshoot this problem you need to verify that the messages from PassGuideClient are
encrypted and signed. You would need to enable logging.
Furthermore, you need to check the content of each message body before it is deserialized to a
.NET object.
How can this be achieved?

There is a WCF (Windows Communication Foundation) service PassGuideService.
The Windows Event Log is used by PassGuideService to log all authorization attempts.
PassGuideService needs to be configured with a behavior to achieve this.
Which behavior is appropriate?

There is a WCF (Windows Communication Foundation) service PassGuideService.
PassGuideService is self-hosted.
The implementations of contracts, the IGreetingService interface, the hosting code, and the
INameService interface are all being displayed in the exhibits.
At the moment the above code fails at line “return String.Format(“Hi there {0}, clientName);”.
You need to tweak the code in order to make it work.

There is a WCF (Windows Communication Foundation) service PassGuideService.
The clients and the service that uses PassGuideService use NetTcpBinding (transaction flow
enabled).
Assuming that the operations PassGuideOP1 and PassGuideOP2 are called within the same
client session, you need to enforce that they are executed within the same transaction context.
Which contract should PassGuideService have?

There is a WCF (Windows Communication Foundation) application PassGuideApp.
There is a WCF (Windows Communication Foundation) service PassGuideService.
The contract of PassGuideService is being displayed in the exhibit.
PassGuideApp is also hosting other services.
PassGuideApp endpoints use SOAP 1.2 bindings with WS-Addressing 1.0.
There is one single lister configured in System.ServiceModel.MessageLogging trace source of the
system.diagnostics configuration section.
Only the messeages that the PassGuideWork operation returns should be logged.

There is WCF (Windows Communication Foundation) service PassGuideService.
A data contract PassGuideContract for PassGuideService is being implemented.
PassGuideContract must be forward-compatible.
The round trips must include the information in PassGuideContract.
It should be able to add ew data members to PassGuideContract.
You do have to follow a strict schema validitiy.
Which interface should be used for PassGuideContract class?
